超冷中子用玻璃Scintillator掺锂面的确定

Determining the 6Li Doped Side of a Glass Scintillator for Ultra Cold Neutrons

Blair Jamieson, Lori Rebenitsch

摘要:

超冷中子(UCN)探测器使用两个视觉上非常相似,微观水平,光学接触的铈掺杂的锂玻璃片已被提出用于高速率UCN实验。这两种玻璃晶体管之间的主要区别在于一侧是6Li耗尽的,而另一侧是Li掺杂的。本文概述了使用AmBe和252Cf中子源以及Si表面势垒探测器确定玻璃堆哪一侧掺杂6Li的方法。当富集侧面对Si表面势垒检测器时,该方法看到在6Li上中子捕获的α和triton能量周围的过量事件。

英文摘要:

Ultracold neutron (UCN) detectors using two visually very similar, to the microscopic level, pieces of optically contacted Cerium doped lithium glasses have been proposed for high rate UCN experiments. The chief difference between the two glass scintillators is that one side is 6Li depleted and the other side Li doped. This note outlines a method to determine which side of the glass stack is doped with 6Li using AmBe and 252Cf neutron sources, and a Si surface barrier detector. The method sees an excess of events around the alpha and triton energies of neutron capture on 6Li when the enriched side is facing the Si surface barrier detector.
